  • Viscosity determination from logarithmic mean ratio of relaxation times
    Patent number: 7511488
    Abstract: A method for determining viscosity, ?, of a fluid downhole, calls for performing a nuclear magnetic resonance (NMR) survey of the fluid; determining a longitudinal relaxation time, T1, and an apparent transverse relaxation time, T2app, for the fluid; forming a ratio R of T1/T2app for the fluid; and determining the viscosity, ?, according to the ratio, R. A computer program product for implementing the method is provided.
    Type: Grant
    Filed: May 1, 2007
    Date of Patent: March 31, 2009
    Assignee: Baker Hughes Incorporated
